Governments are the largest buyer in the world, with aggregate procurement spending of over $12 trillion per year in the OECD. In recent years, a clear trend of consolidation and centralization of government procurement is evident, driven by pressure for efficiency and savings. It is worth understanding what is happening, because these moves are instructive and have implications for the business sector as well.

In March 2025, President Trump signed a presidential executive order to consolidate procurement, making the General Services Administration (GSA) the lead entity for federal procurement of common products and services and government IT contracts. Currently only about 20% of approximately $500 billion in ‘common products and services’ flow through GSA mechanisms, and the plan is to absorb approximately $400 billion, which the procurement chief described as a fourfold increase in size. In fiscal year 2024, approximately $78.2 billion flowed through GSA mechanisms, and an additional $16.3 billion was purchased for other agencies. GSA claims over $60 billion in contract savings since January 2025, and approximately 1,600 contracts that did not meet performance standards were cancelled with savings of approximately $24 million per year. The mechanism relies on category management (ten categories), MAS contracts (MAS contracts are multi-supplier, multi-year framework agreements signed between GSA and commercial vendors) worth approximately $52 billion per year, and the OASIS framework (OASIS was created to handle complex services requiring cross-disciplinary solution integration, such as national project management, complex engineering, research and development, and integrated IT systems).

The United Kingdom: Structural Reform

The United Kingdom took a different path but toward the same direction. The Procurement Act (Procurement Act 2023), which came into effect in October 2024, consolidated four European regulations into a single framework, with publication of 12-month-ahead procurement forecasts, a flexible competitive procedure as default, and a central register for vendor disqualification. Central procurement is carried out mostly through Crown Commercial Service framework agreements, with a target of 33% of spending going to small and medium-sized businesses, although in practice the figure stood at approximately 25.6%.

The European Union and South Korea

In the European Union, central purchasing bodies operate alongside the TED system, through which contracts above the threshold are published with a volume of over €670 billion. South Korea operates KONEPS, a single centralized platform through which over $135 billion per year flows — one of the largest in the world.

Conclusions

Centralization works where demand can be standardized, is highly commercial, and has low customization — exactly the four criteria defined by the American OMB. Complex or mission-unique requirements remain decentralized. Savings come from demand aggregation and category management, not just from building a portal. This is a management insight, not a technological one.

Where to Pay Attention So As Not to Create Mechanisms That Stop Activity

Centralization has limits. It may add bureaucracy, create a one-size-fits-all solution that doesn’t suit everyone, and can generate resistance — every ministry has unique needs: the Department of Homeland Security has security requirements that don’t exist in the Department of Agriculture; the welfare ministry needs special service conditions for specific populations. A framework contract built for the ‘average’ does not cover the edges — and these are sometimes precisely the critical needs. Common products and services sounds simple and right — but the definition is not technical, it is political. Every ministry whose procurement is classified as ‘common’ loses budgetary and strategic control. Hence resistance to classification is not substantive — it is bureaucratic-political. And World Bank research notes that effectiveness depends on the maturity level of the environment.
